The couple spent much of the day focusing on young people and children as they made five stops in east and west Sussex.

Meghan gathered numerous gifts and bouquets of flowers while Harry was spotted patting the head of a baby and hugging a girl who he met at the youth centre.

The newlyweds appeared to be very much still in the honeymoon phase and were seen holding hands and laughing together.

Harry spoke of his love for his wife and how "very happy" he was.

First arriving in Chichester, the duke and the US-born former actress were greeted by excited crowds and then saw a rare copy of the American Declaration of Independence in Edes House.

It is one of only two contemporary handwritten ceremonial manuscript copies.

The other is the signed copy at the National Archives in Washington DC.

Meghan was vocal in her interest and surprise at finding it in Sussex, saying: "My goodness, wow, what are the chances? That's amazing. I just can't believe it."

The duchess wore a camel Giorgio Armani coat, a dark green Hugo Boss skirt and a shirt from And Other Stories paired with nude suede stilettos and a small green bag for her trip to the sunny south coast.

Her hair was tied back in her signature bun and she wore subtle gold jewellery including a number of rings.

Harry was dressed in a grey suit, brown shoes and a white shirt.

At their next stop in Bognor Regis, they officially opened the University of Chichester's Engineering and Digital Technology Park.

The pair donned donned safety goggles to watch an experiment in one of the laboratories then listened to the student chamber orchestra play a piece from Vivaldi's Four Seasons while technology students practised filming and recording the performance in the state-of-the-art sound stage.

The couple chatted with cellist Laura Ritchie, originally from Chicago, and joked that she has lost her accent.

The 44-year-old, who is professor of learning and teaching in the music department, said it was "fantastic, really wonderful and such a privilege" to meet the royals.
